d.grid: -c and -d flags not displaying + and - marks

[richardc]

The -c and -d flags which specify '+' and '-' marks instead of grid lines do not display. If the latter flags are unticked then the grid lines display fine.

It works for me with r63876. Could you see any errors?

[richardc]

I couldn't see any errors with the following commands (selected in GUI):

d.grid -g 00:20 width=4 color=blue <- grid lines visible
d.grid -g -c 00:20 width=4 color=blue <- no grid lines and no '+' marks

I also tried in a Windows version* which again does not show the marks, only grid lines. I'll try updating my GRASS version to see if that helps resolve.

I downloaded the latest d.grid module from svn into my Linux installation, but marks still not visible in Map Display.

[richardc]

I updated my system to 63929, but still the d.grid marks '+' are not displaying. Maybe something unique to my system?

e.g., d.grid -g -c size=00:30 width=6 color=blue fontsize=14

I just tried on command line:

ERROR: Geo-Grid option is not available for LL projection

Other location:

(the spelling is different)

It doesn't seem to available.

d.grid manual says: A geographic grid cannot be drawn for a latitude/longitude or XY projection. When you switch off -g, it will work.

Right. I have changed the message to

ERROR: Geo-grid option not available for LL projection, use without -g/-w

GRASS 7.1.svn (nc_spm_08_grass7):~ > d.grid -g -c size=00:30 width=6 color=blue fontsize=14
WARNING: Geogrid marks not yet implemented

Also here, without -g the marks are shown.

Still a bit funny, in LatLong -g/-w should not be used while e.g. in NC SPM there is no support implemented.

Maybe -g and -w should be commented out?

[martinl]

Still relevant?

[veroandreo]

Tested with grass 76 relbranch, both -c and -d flags work as expected, i.e., respective marks are shown. However, -g and -w do not work in UTM location either, no warning nor error displayed anywhere.

[veroandreo]

Originally reported bug seems to be fixed, therefore closing. For the bug regarding -g and -w flags, see #3831
